Description

Aufhellungsmittel Es wurde gefunden, daß man mit aus wasserlöslichen Aufhellungsmitteln erhältlichen Lacken, d. h. im vorliegenden Fall wasserunlöslichen Produkten, besonders gute Aufhellungseffekte erzielt, wenn man Lacke verwendet, die aus wasserlöslichen, saure Gruppen enthaltenden Aufhellungsmitteln und solchen wasserlöslichen, höhenmolekularen, basischen organischen Verbindungen gewonnen sind, welche praktisch farblos sind bzw. keinen Farbstoffcharakter tragen. Derartige Lacke ergeben vor allem dann wertvolle Effekte bei künstlichen Fasern oder Folien, wenn man sie den zur Herstellung der künstlichen Gebilde dienenden Spinnmassen bzw. Gießmassen einverleibt. Im Gegensatz zu den wasserunlöslichen Erdalkalisalzen von saure Gruppen enthaltenden wasserlöslichen Aufhellungsmitteln führen sie dabei bemerkenswerterweise nicht zu Störungen während der Weiterverarbeitung der Spinn- bzw. Gießmassen.Lightening agents It has been found that one can with off water-soluble Lacquers obtainable by whitening agents, d. H. in the present case, water-insoluble Products, particularly good lightening effects achieved when using varnishes, the whitening agents consisting of water-soluble acidic groups and the like water-soluble, high molecular weight, basic organic compounds are obtained, which are practically colorless or have no coloring character. Such paints result in valuable effects with artificial fibers or foils, if they are used for the production of the artificial structures spinning masses or casting masses incorporated. In contrast to the water-insoluble alkaline earth salts of acidic groups containing water-soluble whitening agents lead them remarkably not to disturbances during the further processing of the spinning or casting masses.

Als wasserlösliche Aufhellungsmittel, die den erfindungsgemäß zu verwendenden Lacken zugrunde liegen können, kommen vor allem Sulfonsäure- oder Carbonsäuregruppen enthaltende Aufheller in Frage, wie sie z. B. in Weber und Martina, »Die neuzeitlichen Textilveredlungsverfahren der Kunstfasern« (1951), S. 139ff., beschrieben sind.As water-soluble lightening agents, those to be used according to the invention Lacquers can be based on, mainly sulfonic acid or carboxylic acid groups containing brighteners in question, as they are z. B. in Weber and Martina, »The modern Textile finishing process of synthetic fibers "(1951), pp. 139ff., Are described.

Als geeignete höhenmolekulare basische Verbindungen seien insbesondere Verbindungen genannt, wie sie zur Erhöhung der Naßechtheiten von Färbungen mit substantiven Farbstoffen Verwendung finden, also z. B. höhenmolekulare Amine oder Polyamine bzw. deren Peralkylierungsprodukte sowie Kondensationsprodukte aus Formaldehyd und -Verbindungen mit der Atomgruppierung Die zur Verwendung gelangenden Lacke können aus den Komponenten in mannigfacher Weise hergestellt sein, beispielsweise durch Vermischung der wäßrigen Lösungen der Komponenten bei gewöhnlicher oder mäßig erhöhter Temperatur; geeignete Mengenverhältnisse der Komponenten sind durch Vorversuche leicht zu ermitteln.Particularly suitable high molecular weight basic compounds are Compounds called as they are used to increase the wet fastness of dyeings with substantive Find dyes use, so z. B. high molecular weight amines or polyamines or their peralkylation products and condensation products from formaldehyde and compounds with the atomic grouping The lacquers used can consist of the components be prepared in many ways, for example by mixing the aqueous Solutions of the components at ordinary or moderately elevated temperature; suitable The proportions of the components can easily be determined by means of preliminary tests.

Die Anwendung der erfindungsgemäß vorgeschlagenen Lacke kann, in der gleichen Weise und für die gleichen Fälle erfolgen, wie dies von anderen lackartigen Aufhellungsmitteln bekannt ist. in etwa 1500 Teilen Wasser wird bei 50 bis 60° C mit einer Lösung von 40 Teilen des höhenmolekularen basischen Kondensationsproduktes aus Formaldehyd und Dicyandiamid in etwa 200 Teilen Wasser versetzt, daß gemäß dem Beispiel des Patents 833 708 hergestellt worden war. Der gebildete Lack wird abfiltriert und in 200 Teilen Wasser mit Hilfe eines nichtionogenen Dispergiermittels vom Typ der Polyglykoläther des Patents 824 949 dispergiert. Die wäßrige Dispersion des Lackes wird dann in dem Maße in eine übliche Lösung von Cellulose und Kupferoxydammoniak eingerührt, daß in 100 Teilen Reincellulose 0,05 Teile des Lackes enthalten sind. Anschließend wird die Spinnmasse in gewohnter Weise versponnen. Die erhaltenen Fasern zeigen gegenüber Fasern, die ohne Zusatz des Aufhellerlackes hergestellt sind, einen deutlichen Aufhellungseffekt.The paints proposed according to the invention can be used in the same way and for the same cases as is known from other paint-like whitening agents. A solution of 40 parts of the higher molecular weight basic condensation product of formaldehyde and dicyandiamide in about 200 parts of water, which had been prepared according to the example of patent 833,708, is added to about 1500 parts of water at 50 to 60.degree. The paint formed is filtered off and dispersed in 200 parts of water with the aid of a nonionic dispersant of the polyglycol ether type of patent 824,949. The aqueous dispersion of the paint is then stirred into a customary solution of cellulose and copper oxide ammonia to the extent that 100 parts of pure cellulose contain 0.05 parts of the paint. The spinning mass is then spun in the usual way. The fibers obtained show a clear lightening effect compared to fibers which are produced without the addition of the brightener lacquer.

_ Beispiel 2 Ein gemäß Beispiel 1 hergestellter Lack von 100 Teilen des Aufhellungsmittels der Formel und 70 Teilen des höhermolekularen basischen Kondensationsproduktes aus Formaldehyd und Dicyandiamid, das gemäß dem Beispiel des Patents 833 708 erhalten war; wird mit Hilfe eines nichtionogenen Dispergiermittels vom Typ der Polyglykolä.ther des Patents 824 949 dispergiert. Die wäßrige Dispersion wird dann in dem Maße in eine übliche alkalische Cellulose-Xanthogenat-Lösung eingerührt, daß in 100 Teilen Reincellulose 0,05 Teile des Aufhellerlackes enthalten sind. Anschließend wird in üblicher Weise versponnen. Die auf diese Weise gewonnenen Fasern zeigen gegenüber Fasern, die ohne Aufhellerlack hergestellt sind, eine ausgezeichnete Aufhellung. Beispiel 3 Eine Lösung von 100 Teilen des Aufhellungsmittels der Formel in 2000 Teilen Wasser wird bei 20 bis 30° C bis zur völligen Fällung mit der wäßrigen Lösung des höhermolekularen basischen Kondensationsproduktes versetzt, daß gemäß Beispiel 2 des Patents 895 439 durch Umsetzung einer Guanidinsalz Dicyandiamid-Mischung mit Formaldehyd in Gegenwart von Ammoniumsalzen hergestellt war. Die Fällung wird isoliert und in 200 Teilen Wasser mit Hilfe eines nichtionogenen Dispergiermittels vom Typ der Polyglykoläther des Patens 824 949 dispergiert. Die wäßrige Dispersion wird dann in dem Maße in eine übliche Lösung von Cellulose in Kupferoxydammoniak eingerührt, daß in 100 Teilen Reincellulose 0,05 Teile des Aufhellerlackes enthalten sind. Anschließend wird in -üblicher Weise versponnen. Die so hergestellten Fasern zeigen gegenüber Fasern, die keinen Aufhellerlack enthalten, einen sehr guten Aufhellungseffekt.Example 2 A paint produced according to Example 1 from 100 parts of the whitening agent of the formula and 70 parts of the higher molecular weight basic condensation product of formaldehyde and dicyandiamide, which was obtained according to the example of the patent 833,708; is dispersed with the aid of a non-ionic dispersant of the polyglycolic ether type of patent 824,949. The aqueous dispersion is then stirred into a customary alkaline cellulose xanthate solution to such an extent that 100 parts of pure cellulose contain 0.05 part of the brightener lacquer. It is then spun in the usual way. The fibers obtained in this way show an excellent lightening compared to fibers which are produced without a brightener varnish. Example 3 A solution of 100 parts of the whitening agent of the formula in 2000 parts of water at 20 to 30 ° C until complete precipitation is added to the aqueous solution of the higher molecular weight basic condensation product that was prepared according to Example 2 of Patent 895 439 by reacting a guanidine salt dicyandiamide mixture with formaldehyde in the presence of ammonium salts. The precipitate is isolated and dispersed in 200 parts of water with the aid of a nonionic dispersant of the polyglycol ether type of patent 824,949. The aqueous dispersion is then stirred into a customary solution of cellulose in copper oxide ammonia to the extent that 100 parts of pure cellulose contain 0.05 part of the brightener lacquer. It is then spun in the usual manner. The fibers produced in this way show a very good brightening effect compared to fibers which do not contain any brightener varnish.
